Abstract

PURPOSE: To provide a method for selectively canceling print jobs to have been transmitted to a printer in a computer or the printer without turning off the printer. CONSTITUTION: A processor of a printer checks that a printing order is received from a computer through an input/output port(S201), and stores a transmitted printing data in a memory(S202). In addition, when a printer engine is ready to work by the processor(S203), an engine controller sends the printing data in the memory to the engine, which performs a print job(S204). Concurrently with performing the print job, the processor checks that a print cancel key is selected among several keys in an operating panel(S205), and then controls the controller to stop the engine and further checks that pages to cancel the print job are inputted(S206). Next, the processor detects the printing data corresponding to the pages from the memory(S207), and deletes the detected data (S208). Finally, the processor verifies that the print job is completed(S209) and closes a printing process(S210).

Description

How to cancel a print job

The present invention relates to a method of canceling a print job, and more particularly, to selectively cancel a print job of a print data remaining in a printer by a computer or a printer without turning off the power of a printer that receives data from a computer and prints the data. To cancel a print job.

Generally, a printer is an office device connected to a computer and outputs a result on paper. The printer receives a document or image data created or edited on the computer, converts it into a printing language suitable for the printing conditions, and prints ink or toner. It is a device that outputs to paper using colored dyes.

Recently, due to the complexity of the office environment and the increase of office equipment and personal computers that are essential for the office environment, the office environment has gradually changed to a networking environment, and the data of each personal computer is connected by connecting the personal computers in the office to one network.

When a user prints a document created using various applications of the computer, the print data is stored in a spooler to reduce the processing delay when transferring data between the computer and the peripheral device. It is sent to the printer in units, and the printer receives and prints the print data in units of pages. If the user wants to cancel the print job, the print data remaining in the spooler without being sent to the printer can be deleted from the computer, but the print data sent to the printer cannot be deleted until the printer is turned off.

According to the conventional method for canceling a print job, the following problems occur.

First, if the user executes a print command incorrectly or checks the printed output and no longer wants to print it, canceling the print job from the computer cancels the print data queued in the spooler but print data sent to the printer. Is not canceled unless the printer is turned off. Therefore, the print data sent to the printer is continuously printed even if the user does not want to output, resulting in waste of printing paper or toner.

Second, if a user executes a print command incorrectly or checks the printed output and no longer wants to print, the printer can be turned off to cancel the print job. All print data stored in the memory will be deleted. Therefore, when the printer is shared by several people, there is a problem that the printing of another person is canceled.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to print the print data sent to the printer without turning off the printer when the print data is not sent to the printer. The present invention provides a method of canceling a print job that can be selectively canceled by the user.

When the print preparation is completed as described above (S203), the engine controller 10 transmits the print data stored in the memory 9 to the printer engine 11 under the control of the printer central processing unit 7. 11) performs a print job using the transmitted data (S204).

The printer central processing unit 7 performs a print job and at the same time checks whether a cancel print key is selected among a plurality of keys of the operation panel 8 of the printer (S205), and if a key to cancel the print job is selected, The engine controller 10 is controlled to stop driving of the printer engine 11, and it is determined whether there is an input of a page for canceling the print job (S206).

That is, among a plurality of users connected to a network and sharing a single printer, a predetermined user executes a print command to output a document created by the application 3 of the computer to the printer, and then incorrectly executes the print command. Alternatively, you can check the printed output and cancel the print command in progress when you do not want to print any more. However, at this time, the print data queued in the spooler is deleted, but the print data that has been transferred to the printer is not deleted. Therefore, in order to delete the print data stored in the memory 9 of the printer, the user selects a preset print cancel key for canceling a print job from among a plurality of keys of the operation panel 8 of the printer (see Fig. 8A).

When the printer canceling key is selected by the user, the printer central processing unit 7 outputs a message for selecting the printing canceling range on the display window 8a of the operation panel 8 so as to select the printing canceling range (Fig. 8b).

That is, the printer central processing unit 7 displays a message so that when the user selects the print cancel key, the user switches to the page input mode and inputs a page to be deleted on the display window 8a of the operation panel 8. When the message 'Print Cancel Start Page' is displayed on the display window 8a, the user inputs a desired print cancel start page using a preset key (e.g., up / down keys (▲ / ▼)) and inputs a selection key. When the message 'Print Cancel End Page' is displayed, the user inputs a desired print cancel end page using a preset key and then enters a selection key. The page information is stored in a predetermined position of the memory 9. At this time, initial values of the print cancel start page and the print cancel end page are set to '0' (see Fig. 8C).

When a page to be deleted from the print data stored in the memory 9 is input by the user, the central processing unit 7 for the printer detects the data corresponding to the input page in the memory 9 (S207), and the detected data. Delete (S208).

When the central processing unit for the printer 7 deletes the data corresponding to the page for canceling the print job selected by the user, the printing is completed (S209).

When the print preparation is completed as described above (S303), the engine controller 10 transmits the print data stored in the memory 9 to the printer engine 11 under the control of the printer central processing unit 7, and the printer engine ( 11) performs a print job using the transmitted data (S304).

The printer central processing unit 7 performs a print job and at the same time checks whether a button for canceling a print job is input from the computer (S305), and when a button for canceling a print job is input, the user who executes a print cancel command. ID is detected (S306).

When the user's ID is detected, the printer central processing unit 7 checks whether a print cancel range is input from the detected user (S307).

That is, among a plurality of users connected to a network and sharing a single printer, a predetermined user executes a print command to output a document created by the application 3 of the computer to the printer, and then incorrectly executes the print command. Alternatively, you can check the printed output and cancel the print command in progress when you do not want to print any more. However, at this time, the print data queued in the spooler is deleted, but the print data that has been transferred to the printer is not deleted. Thus, in order to delete the print data stored in the memory 9 of the printer, the user selects a preset print cancel button for canceling the print job in the print manager 2 of the computer (see Fig. 7A).

The central processing unit 1 for the computer displays the screen on the computer so that the print cancel range can be selected when the cancel print button is selected. The user selects a predetermined range (for example, one specific document and one page of one specific document among all documents created and sent to the printer or sent to the printer) among the printed cancellation ranges. When selected, the central processing unit 1 for the computer transmits the print cancel range set by the user to the printer (see Fig. 7B).

When the print cancel range set as described above is input, the printer central processing unit 7 detects data corresponding to the input print cancel range from the document transmitted by the detected user ID in the memory 9 (S308), The detected data is deleted (S309).

When the deletion of the detected print data is completed, it is checked whether the printing is completed (S310), and when the printing is completed, the printing job is terminated (S311), and the flow returns to the initial standby state. Here, if the printing is not completed and the print data exists in the memory 9, the process is repeated from step 304 (S304) of printing the data stored in the memory 9.

On the other hand, if the print cancel button is not input in step 305 (S305) of checking whether a button for canceling a print job is input from the computer, the process is repeatedly performed from step 310 (S310) of checking whether the print job is completed.

Therefore, the user can directly delete the print data transferred to the printer by using a preset button in the print manager of the computer without turning off the printer.

The operation of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

<3rd Example of this invention>

5 is a flowchart illustrating a method of canceling a print job according to a third exemplary embodiment of the present invention.

Referring to FIG. 5, the central processing unit 20 for a printer checks whether print data is received from a computer through the printer input / output port 29 (S501), and when the print data is received, the DMA processor 21 The data transmitted from the computer is stored in the memory 23 and the location information of the data is detected (S502).

The printer central processing unit 20 checks whether the printing preparation is completed (S503), and when the printing preparation is completed, the head DMA 22 stores data stored in the memory 23 under the control of the printer central processing unit 20. And the positional information of the data detected by the DMA processing section 21 to the printhead control logic 25. The printhead control logic 25 transmits the data and the positional information to the printhead 26 so that data can be printed according to the positional information of the data transmitted from the head DMA 22 (S504).

The print head 26 is moved by the carrier motor 28 driven by the control of the carrier motor control logic 27, and prints by injecting ink or toner corresponding to the transmitted data according to the position information of the transmitted data. Perform the operation (S505).

The central processing unit 20 for the printer checks whether the print job is completed (S506), terminates the print job if the print job is completed (S507), and if the print job is not completed, a plurality of operation panels 24 of the printer. It is checked whether a print cancel key is selected among the four keys (S508).

If a key for canceling a print job is selected, the central processing unit 20 for the printer controls the printhead control logic 25 to stop driving the printhead 26, and there is an input of a page to cancel the print job. It is determined whether or not (S509).

That is, a predetermined user among a plurality of users connected to a network and sharing and using one printer executes a print command to output a document created by the application program 12 of the computer to the printer, and then incorrectly executes the print command. Alternatively, you can check the printed output and cancel the print command in progress when you do not want to print any more. However, at this time, the print data queued in the spooler is deleted, but the print data that has been transferred to the printer is not deleted. Therefore, in order to delete the print data stored in the memory 23 of the printer, the user selects a preset print cancel key that cancels a print job from among a plurality of keys of the operation panel 24 of the printer (see Fig. 8A).

If the printer cancel key is selected by the user, the printer 20 outputs a message for selecting the print cancel range on the display window 24a of the operation panel 24 so as to select the print cancel range (Fig. 8b).

In other words, the printer central processing unit 20 displays a message so that when the user selects the print cancel key, the user enters the page input mode and inputs a page to be deleted on the display window 24a of the operation panel 24. . When the message 'Print Cancel Start Page' is displayed on the display window 24a, the user inputs a desired print cancel start page by using a preset key (e.g., up / down keys (▲ / ▼), inputs a selection key). When the message 'Print Cancel End Page' is displayed, the user inputs a desired Print Cancel End Page using a preset key and then inputs a selection key. The page information is stored in a predetermined position of the memory 23. At this time, initial values of the print cancel start page and the print cancel end page are set to '0' (see Fig. 8C).

When a page to be deleted from the print data stored in the memory 23 is input by the user, the printer central processing unit 20 inputs a reset signal as much as the input page (S510).

A method of canceling a print job of data transmitted to a printer engine when a reset signal is input will be described with reference to the block circuit diagram of FIG. 9.

The printhead control logic 25 transmits the data received through the head DMA 22 and the position information of the data to the printhead 26. At this time, when the reset signal is input, data corresponding to the page input by the user among the data transmitted from the printhead control logic 25 to the printhead 26 is deleted by the reset signal. Therefore, data is not transmitted to the printhead 26, but only positional information of the data is transmitted.

The printer central processing unit 20 inputs the reset signal for the input page, and then branches to step 505 (S505) for performing a print job and repeatedly performs the same. Here, since the printer engine 26 deletes the data by the reset signal and receives only the location information of the data, the page on which the user inputs to cancel the print job is outputted without paper.

On the other hand, if there is no input of the page within the predetermined time in step 509 (S509) of determining whether there is an input of the page to cancel the print job, the printer central processing unit 20 stores the whole stored in the memory 23. After inputting the reset signal for each page (S511), the process branches to step 505 (S505) for performing a print job and repeats.

Therefore, the user can directly delete the print data which has been transferred to the printer by using a predetermined key provided on the operation panel of the printer without turning off the printer.

<4th Example of this invention>

6 is a flowchart illustrating a method of canceling a print job according to a fourth embodiment of the present invention.

Referring to FIG. 6, the central processing unit 20 for a printer checks whether print data is received from a computer through the printer input / output port 29 (S601), and when the print data is received, the DMA processing unit 21 is performed. The data transmitted from the computer is stored in the memory 23 and the location information of the data is detected at step S602.

The printer central processing unit 20 checks whether the printing preparation is completed (S603), and when the printing preparation is completed, the head DMA 22 stores data stored in the memory 23 under the control of the printer central processing unit 20. And the positional information of the data detected by the DMA processing section 21 to the printhead control logic 25. The printhead control logic 25 transmits the data and the positional information to the printhead 26 so that data can be printed according to the positional information of the data transmitted from the head DMA 22 (S604).

The print head 26 is moved by the carrier motor 28 driven by the control of the carrier motor control logic 27, and prints by injecting ink or toner corresponding to the transmitted data according to the position information of the transmitted data. Perform the operation (S605).

The printer central processing unit 20 checks whether the print job is completed (S606), if the print job is completed, ends the print job (S607), and if the print job is not completed, a button for canceling the print job from the computer is Check whether the input (S608).

When a button for canceling a print job is input from the computer, the printhead control logic 25 is controlled to stop driving of the printhead 26, and a user ID for inputting a print cancel button is detected (S609). When the user ID is detected, the central processing unit 20 for the printer detects a print cancel range input by the detected user (S610).

That is, a predetermined user among a plurality of users connected to a network and sharing and using one printer executes a print command to output a document created by the application program 12 of the computer to the printer, and then incorrectly executes the print command. Alternatively, you can check the printed output and cancel the print command in progress when you do not want to print any more. However, at this time, the print data queued in the spooler is deleted, but the print data that has been transferred to the printer is not deleted. Therefore, in order to delete the print data stored in the printer's memory 23, the user selects a preset print cancel button for canceling the print job in the print manager 11 of the computer (see Fig. 7A).

The central processing unit 10 for the computer displays the screen on the computer so that the print cancel range can be selected when the cancel print button is selected. The user selects a predetermined range of displayed print cancellation ranges (for example, one particular document and one page among all documents created in the application 12 and sent to the printer or all documents sent to the printer). When selected, the computer central processing unit 10 transmits the print cancel range set by the user to the printer through the computer input / output port 15 (see FIG. 7B).

When the print cancel range set as described above is detected, the central processing unit 20 for the printer checks whether the data transmitted by the detected user ID is printing (S611), and the data transmitted by the user who inputs the print cancel button is printed. If so, the printer central processing unit 20 inputs as many reset signals as the pages corresponding to the detected print cancellation range (S612).

A method of canceling a print job of data transmitted to a printer engine when a reset signal is input will be described with reference to the block circuit diagram of FIG. 9.

The printhead control logic 25 transmits the data received through the head DMA 22 and the position information of the data to the printhead 26. At this time, when the reset signal is input, data corresponding to the page input by the user among the data transmitted from the printhead control logic 25 to the printhead 26 is deleted by the reset signal. Therefore, data is not transmitted to the printhead 26, but only positional information of the data is transmitted.

The printer central processing unit 20 inputs a reset signal corresponding to the page corresponding to the printing cancellation range, and then branches to step 605 (S605) of performing a print job and repeats the process. Here, since the printer engine 26 deletes the data by the reset signal and receives only the location information of the data, the page on which the user inputs to cancel the print job is outputted without paper.

Therefore, the user can directly delete the print data transferred to the printer by using a preset button in the print manager of the computer without turning off the printer.
